Question

An object is starting from rest and moving with an acceleration of 2m/s what will be the velocity after 10seconds

Answer 1

Answer:

GIVEN:

V = 2m/s.

t = 10 sec.

ACCORDING TO QUESTION.

u =0

v = 2 m/s,

s = 10 m

v² = u² + 2 a s

2² = 0 + 2 × 10 × a

a = 4/20 = 0.25 m/s²

Now,

v² = u² + 2 a s

v ² = 0 + 2 × 0.25 × 4

v² = 2

v = √2

v = 1.414 m /s.
